These times can vary based on factors such as the athlete's training, technique, and physical condition. **

To improve your performance in the 75m sprint, it's important to focus on explosive speed and power. Incorporate plyometric exercises like box jumps and bounding to improve your explosive strength. Work on your sprinting technique, paying attention to your start, acceleration, and maintaining proper form throughout the race.

The calorie expenditure for road cycling and mountain biking can vary based on factors such as intensity, terrain, and duration. Generally, road cycling on flat terrain at a moderate pace can burn around 400-600 calories per hour, while mountain biking on varied terrain with hills and obstacles can burn around 500-800 calories per hour. The higher calorie expenditure in mountain biking is due to the increased effort required to navigate the challenging terrain and obstacles. Overall, mountain biking tends to result in a higher calorie expenditure compared to road cycling. **

It is not possible to run a 75m sprint in 106 seconds, as that time is much longer than it would take to cover that distance. A typical time for a 75m sprint would be around 9-10 seconds for a male athlete and 10-11 seconds for a female athlete. Therefore, it is important to re-evaluate the timing and performance for a 75m sprint. **

Whether or not you should stop mountain biking depends on your personal circumstances and reasons for considering stopping. If you are experiencing physical pain or injury from mountain biking, it may be wise to take a break and seek medical advice. If you are feeling burnt out or no longer enjoying the activity, it may be beneficial to explore other forms of exercise or outdoor activities. Ultimately, the decision to stop mountain biking should be based on your own well-being and enjoyment. **

Mountain biking is all about the thrill of exploring rugged terrain, challenging yourself physically and mentally, and connecting with nature. It's about pushing your limits, feeling the rush of adrenaline as you navigate steep descents and technical obstacles, and enjoying the freedom of riding through breathtaking landscapes. Mountain biking is also a community of like-minded individuals who share a passion for adventure and the outdoors, and it's a way to escape the hustle and bustle of everyday life and immerse yourself in the beauty of the natural world. **

When going mountain biking alone, it is important to be well-prepared and take necessary safety precautions. Make sure to inform someone of your planned route and expected return time. Pack essential items such as water, snacks, a first aid kit, and a fully charged phone. Choose a trail that matches your skill level and experience, and always ride within your limits. Lastly, stay alert, be aware of your surroundings, and trust your instincts if you encounter any risky situations. **

The suitable size for mountain biking depends on the rider's height and personal preference. Generally, a medium-sized frame is suitable for most riders, but taller riders may prefer a large frame for a better fit. It's important to consider the reach, standover height, and top tube length when choosing the right size for mountain biking to ensure a comfortable and efficient ride. Riders should also test ride different sizes to find the best fit for their body and riding style. **
